Proof that girls are evil:
First we state that girls require time and money.
Girls = Time x Money

And as we know "time is money."
Time = Money

Therefore:
Girls = Money x Money = (money)square

And because "money is the root of all evil":
Money = (Evil)square root

Therefore:
Girls = [(Evil)square root]square

And we are forced to conclude that:
Girls = Evil
-----------------------------
Proof that men are worse than girls

First we state that men need time, money, girls and sex, so
Men = Time x Money x Girls x Sex

And as we all know "time is money"
Time = Money

Therefore:
Men = Money x Money x Girls x Sex

And we all know men want girls as many as possible because they want to have sex as many as they can.
For them~ Girls = Sex

As for men's proof that "girls are evil"
Girls = evil
so Evil = Sex

Therefore:
Men = (Money)square x Evil x Evil = (Money)square x (Evil)square

And because "money is the root of all evil"
Money = (Evil)square root

Therefore:
(Money)square = Evil
Men = Evil x (Evil)square = (Evil)cube

Men's proof
Girls = Evil

Girls proof
Men = (Evil)cube---> Men are worse than evil.

So we are forced to conclude that Men are worse than Girls.
